[Dynamics of the rythm of the isolated and intact frog heart].
This study was designed to examine the changes of the isolated frog's heart rate as a function of the time in the two time intervals: 20-95 min and 95-170 min after hearts were prepared. The heart rate decreased in these intervals quite linear but average slope between 20-75 min was significantly steeper than in the time interval 95-170 min. It was shown that the difference in the heart rate response induced by the increasing temperature in intact animals and isolated hearts partly might be explored by this decrease in the isolated frog's heart rate with time.
